I have two of these modules, based on the Nordic905 chips
http://www.rfdesign.co.za/Files/5645456/RFOEM%20manual1.5%20Montar%20LH%20pdf.pdf
and want to try them to start with as simplex TxRx links, and perhaps later progress to handshaking.
To avoid the RXD TXD of the normal serial programming, I am planning to use newsoftserial ( which I have working fine on my gps clocks)
I cant seem to find any basic description of the newsoftserial library, I need to try firstly to send some data from the Tx Arduino board to the Rx one.
I normally use virtualwire to a simple RF transmitter module, but these modules have a load of extra handshaking stuff in them, so I dont think it will work.
I have been trying all day , but I am missing something, can anyone point me to a simple sketch to try and establish just a one way link, that I can build on?
I must confess to also being confused with RX and TX names on the chips and modules, you connect Rx to Tx, and vice verca , but then you are told to connect a 1k resistor in the RX line if the Vcc is different - which Rx ? ( OK that can be worked out ) but in setup for newsoftserial we define
NewSoftSerial mySerial(15, 14);
Which is Rx and which is Tx ? and to which end are we referring? I worked it out but if you didn't have a 1k resistor in the right line you could blow the GPS transceiver or whatever.
